Alright, lets get started.
The length of first fence = [tex] \frac{15}{16}[/tex]
The length of second fence = [tex] \frac{7}{8}[/tex]
The length of third fence = [tex] \frac{7}{16}[/tex]
Total length of all three fence = [tex] \frac{15}{16}+\frac{7}{8}+\frac{7}{16}[/tex]
For adding them, we need to first make common denominator
Total length of all three fence = [tex] \frac{15}{16}+\frac{2*7}{2*8}+\frac{7}{16}[/tex]
Total length of all three fence = [tex] \frac{15}{16}+\frac{14}{16}+\frac{7}{16}[/tex]
Now we have common denominator, so
Total length of all three fence = [tex] \frac{15+14+7}{16}[/tex]
Total length of all three fence = [tex] \frac{36}{16}[/tex]
36 and 16 could be simplified with 4, so
Total length of all three fence = [tex] \frac{9}{4}[/tex] : Answer
Hope it will help :)
